Consolidation of a Layer under a Strip Load

Abstract

A previously described finite element program is used to solve for the consolidation behavior of an elastic soil under strip loading. A parametric study is made of the effects of loading geometry, drainage, and material constants. The results indicate that the ratio of half width of load to depth of soil for drainage at the top (a/H) has little effect when a/H is greater than 1 and that there is some acceleration of settlement when a/H is smaller. Poisson's ratio of the soil has very little effect. The anisotropic permeability has the largest effect, and its influence is described in two charts. With these provisions, one-dimensional theory can be used in many cases.
